Real nice image. I really like the background. Well composed and love the pose of the bird. Like if it has spotted its next meal. Looks pretty sharp to me despite using such a low shutter. Well done.
Wow, what a bird! Sharp with lots of details. Nice bg too.
Moving him a bit higher in the frame would perhaps work well.
Nicely done. Looks really great for that iso and low ss.
Love the soft light and nice feather detail. Good choice to push your ISO here; noise is well-controlled. I agree with the comments about more room at the bottom. I think there's a magenta/blue color cast to the image.
Rakesh, impressive sharpness and detail, and this guy certainly has a fair size bill. I like how the bill follows the line of the OOF leaves in the BG.
Love the image and the lichen covered perch. The only nit that I have is that something looks odd to me in the wing feathers. It looks like they might be sharpened a bit too much when I compare them to the breast and cap feathers, but that just may be the fact that they are blue and so show the edging very differently so take the comment for what it's worth.
Composition wise, the centered head position works for me. However, the bird seems to be looking at something and I can't tell what. I would prefer to "know" what the bird was looking at or a different HA with more "eye contact". (I think that might be why some would like more space below)
Exposure wise, I think it's a bit flat and slightly off on color.
All I did was a levels adjustment using the white patch on the head for white point and the eye for the black point. then reduced the white output level to 245.
